Time loop has engaged. Time travel is always interesting (I wrote a whole post on it, after all). The perception of time in this show are fairly consistent with my own theory. Basically, the fairies created their own time/space zone and are transporting Watashis from different timelines to it. You could think of it as the “original” Watashi is being transported into the other Watashis’ timelines to live out their stuff for them while they’re being collected. Of course, this doesn’t explain why they all have the same memories, though.
But theories aside, it looks like this show is actually moving backwards in time since Watashi hasn’t met the assistant yet. I wonder how long they’ll keep showing the past rather than advancing further. Oh well…time travel is always fun…it’s possible they’ve been ordering the episodes like this on purpose so they can make references to the previous episodes in this time travel arc. We’ll have to see.
